Cross sections for the 32S(p, p′γ)32S nuclear reaction used for the profiling of sulphur on materials surfaces

Improved energy resolution of a cyclotron beam for RBS measurements

“…The improvement in resolution has been measured by recording the resonance width of a 32 S(p,p 0 c) 32 S reaction [4]. A PbS thick target was placed in the center of a vacuum chamber situated in area 2 (see Fig.…”

Differential cross section measurements of the 32S(d,p)33S reaction for nuclear reaction analysis purposes

“…In order to meet this goal, various ion beam analysis (IBA) methods have been proposed so far [3][4][5][6][7][8]. Among them, only the resonant particle gamma-ray emission (R-PIGE) can simultaneously provide accurate quantitative and depth profiling data.…”

“…Among them, only the resonant particle gamma-ray emission (R-PIGE) can simultaneously provide accurate quantitative and depth profiling data. The proposed resonance at 3379 keV of the 32 S(p,p 0 c) reaction (width: 1 keV) has frequently been applied to the sulfur determination and profiling [4]. On the other hand, this method is time consuming, strictly isotope specific and provides no information for the other light elements present in the samples.…”

Investigation of copper patinas using ion beam analysis and scanning electron microscopy

“…The code RUMP was used for analysis of the RBS spectra. 14,15 Deuteron bombardment of the samples, along with the backscattered particle spectrum, gave the required data for determination of the oxygen depth distribution in the near-surface layers of the patinas by means of the 16 O d,p 17 O nuclear reaction. 16 Detection of the protons emitted by the deuteron-induced reaction on oxygen and of the backscattered deuterons was performed simultaneously by a surface barrier detector set at an angle of 135°to the beam direction.…”

“…The sulphur depth distribution was determined using the 3.379 MeV resonance of the 32 S p,p 0 32 S reaction. 17 Detection of the 2.230 MeV -rays emitted by the 32 S p,p 0 32 S reaction was performed with a high-purity Ge detector set at an angle of 90°to the proton beam direction. The energy of the proton beam supplied by the accelerator was varied in steps of 30-50 keV within the region 3.375-3.700 MeV.…”
